Ego Death

You remind a creature of its moral failings. The target must make a wisdom saving throw against your spell save DC.

On a failure, the target relives the worst thing they've done to another living creature from that creature's perspective.
The target is under the effect of the stunned condition for the duration. A creature stunned by this spell can make another wisdom saving throw at the end of each of its turns.

If the creature has not committed a particularly egregious sin, the spell fails. The caster learns the memory the target relives.
